Abstract

Fabrication of Light Ceramic Aggregate by Authothermal Sintering of Power Plant Ashes in the Rotary Furnace The inexpensive and reliable technology of the production of ceramic aggregate from coal ash, coal dust and mineral cement (clay, bentonite) optionally organic cement has been developed. The tecchnology is based on the method of sintering in high temperature. The conception of workings and the way of performance of the dryer of the humid aggregate and the rotary furnace in which the process will be carried on with no addition of the external fuel have been also developed. The implementation studies, partly granted by European Union, have been continued. The studies consisted ass follows: the laboratory research into the drying of coal ash granules, the compilation of technical parameters for the performance of a new shaft dryer by building semi-commercial model and defining parameters of working, the studyon the sintering in modernized semi-commercial rotary furnace. Currently process desing for final technical installation are being developed.
